Unlike 'Doctor' and 'Zero', 'Father' was a title Sigma had never properly prepared himself for, but for all the trouble it had caused him he was at last ready to accept it. By far the worst trait of his 'gift' were the dozens of timelines from which he remembered Kyle's death - and one in particular was still fresh in his mind. For an instant, Sigma's face fell with emotion, but he immediately collected himself with sternness he'd rehearsed in his hiding place. This was no time for a touching reunion, as much as he would appreciate a clue from Kyle to tell him how he was expected to act. For now, Kyle's father would remain as cold and calm as possible until the two of them were out of danger.

"They brought you, too," Sigma answers in an exhausted daze. There was much to take in, and the stress and hunger fatigued him. "I am sorry," he says, and it is an apology for more than their circumstances.

And unlike the younger man, Sigma was not troubled by their new status as competitors. As far as Dr. Klim was concerned, Kyle would unquestionably be the victor.
